They may have been a little late for Halloween, but Week 10 in the NFL may be best known for the zombie-like invasion of the backup quarterbacks. Because of injuries, several teams had to start their second-stringers; others were forced to go to them when their starters went down.

The most successful of the bunch turned out to be lightly regarded Kellen Clemens of the St. Louis Rams. Clemens got some help from touchdowns by his defense and special teams -- but was quietly effective in his own right, completing nine of 16 passes for 247 yards and two touchdowns.

Those two TDs both went to the breakout star of the week, rookie wide receiver Tavon Austin, who caught scoring passes of 57 and 81 yards -- and also returned a punt 98 yards for another touchdown. It was the kind of big-play day fantasy owners had yet to see all season from Austin. In fact, Austin had only 207 receiving yards and two touchdowns in the Rams' previous nine games.

Unlike the Nick Foles-to-Riley Cooper connection that paid dividends for a second consecutive week (Cooper had two more TD receptions on Sunday), don't bank on Clemens-to-Austin carrying fantasy teams to new heights going forward. Those were Austin's only two receptions the entire game.

Elsewhere on Sunday:

-- Chicago Bears quarterback Jay Cutler returned after being sidelined for two weeks with a groin injury -- only to leave the game early with an ankle sprain. Cutler was 21-of-40 for 250 yards. Both he and second-stringer Cade McCown (6-for-9, 62 yards) connected with star wideout Brandon Marshall for touchdowns, so no matter who's under center going forward Marshall will still be an every-week start.

-- Taking over the Green Bay Packers offense for the injured Aaron Rodgers, backup quarterback Seneca Wallace lasted all of one series before leaving with an injury of his own (groin). Enter undrafted practice squad promotion Scott Tolzien, who hit on 24-of-39 passes for 280 yards, one touchdown and two interceptions.

The Packers said Tolzien did enough to earn another start (Rodgers will miss at least four weeks with a broken collarbone), but all receivers should be downgraded. Jarrett Boykin led the receiving corps with eight catches for 112 yards. Tight end Brandon Bostick caught the TD pass.

-- Tennessee Titans QB Jake Locker also exited early with a foot injury. (Insert your own foot/Locker joke here.) He was replaced by veteran Ryan Fitzpatrick, who completed 22-of-33 passes for 264 yards and a pair of touchdowns.

Fitzpatrick also ran for another score. Although he didn't throw an interception, Fitzpatrick fumbled late in the fourth quarter while being sacked and it was returned for a touchdown as the Jacksonville Jaguars won their first game of the season.

-- Out since suffering a broken leg in the preseason, New York Giants running back Andre Brown took over for an ineffective Peyton Hillis and made up for lost time. Brown carried the ball 30 times for 115 yards and scored a touchdown. Brown was the Giants' workhorse last season,so there's every reason to expect him to resume that role down the stretch. As long as he's able to practice this week after getting all those carries, Brown is the running back to own for the Giants.
